Module not Installed - Qml issue with included .pro files (iOS)



  • Qml files not refenced in the same pro as the main.qml may cause the runtime error "Module '<module name>’ is not installed", This problem seems to only affect iOS.

    My Project structure is something along the lines of:

    	MyLocalProject\
    		MyProject.pro
    		qml.qrc
    		qml\
    			main.cpp
    			main.qml
    		..
    	CommonProject\
    		CommonProject.pro
    		commonqml.qrc
    		qml\	
    			QmlObject.qml
    

    qrc qresource prefixes are all “/” so expected import path is the same “qrc:/”

    MyProject.pro includes "../CommonProject/CommonProject.pro"
    main.qml has a QmlObject
    QmlObject.qml has the line "import QtQml.StateMachine 1.0"

    This runs fine on Android, MacOs and Windows.
    but on iOS this will come up with the runtime error "Module 'QtQml.StateMachine' is not installed"

    adding the line "import QtQml.StateMachine 1.0" to main.qml solves this, however this is not an ideal solution as it means when I add a qml file to commonqml.qrc
    I need to make sure any Qml modules that are referenced in it are also added to main.qml.
